Hi Kristine,
I have the same problem as you and I have not cheated or shared my interracial fantasy with my husband yet either. I thought about leaving hints like faking an email address and sending his email pictures of black lovers and beautiful wives, but I am to scared to even do that!
It would be so wonderful to share this fantasy, but remember it could wrong and you will loose your husband forever. That's what keeps me from taking it any further than a fantasy!
Good luck sweetie!
Kisses, Kristy
